Combining a compulsive read with rigorous academic analysis, this book tells the real-life stories of drug dealers involved in county lines networks, including their methods, motives and misfortunes. Conventional wisdom surrounding county lines often portrays drugs runners as exploited victims and gang proliferation as a market-driven exercise, and suggests a business model facilitated exclusively by smart phone technology and routinely regulated by violence. Aimed at students, scholars, practitioners and policymakers, this myth-busting, accessible book offers a novel way of thinking about county lines in relation to gangs and serious organised crime and presents new ideas for drug crime prevention, intervention and enforcement.
